8 Claims, 14 Drawing Figures PJJENTEU FEB I 8 i975 SHEET 10F 4 NM mm 22%E1 mm 6 E FLY APPARATUS FOR FORMING DISPLAY PACKAGES The presentinvention relates to an apparatus for forming display packages, and moreparticularly relates to an apparatus for forming a display packageconsisting of a card, a transparent blister and a product contained inthe blister.

A common form of display packaging used in retail stores today is a socalled blister pack." This package includes a cardboard backing card; atransparent, plastic blister which is raised above the surface of thecard; and a product positioned between the raised blister and thesurface of the card. Typical items of commerce displayed in such blisterpacks are lipsticks, nail polish, pens and pencils, small tools andhardware, and any other small item of merchandise. The advantages of theblister pack are twofold. The first is that the item to be sold isclearly visible through the transparent blister, and the second is thatthe item can not easily be pilfered since it is enclosed by a blisterand mounted to a card which is much larger than the item itself.

In the past there have been various attempts to provide devices forautomatically forming blister packs. However, many of these prior artattempts have not been totally successful or economical since theprocess of formation includes a complicated series of steps, whichnecessarily required the use of complicated and expensive equipment.

It is therefore, an object of the present invention to overcome thelimitations and drawbacks associated with the prior art devices and toprovide a new and improved device for forming display packages.

Another object of the present invention is to provide an apparatus forforming display packages of the type including a transparent blistercontaining a product to be displayed and a blister supporting card.

A further object of the present invention is to provide a displaypackage forming apparatus which can automatically form packages at ahigh rate of speed.

A further object of the present invention is to provide display packageforming apparatus which is relatively simple and inexpensive to produce,yet which will operate satisfactorily for extended periods of timewithout undue maintenance or repair.

A further object of the present invention is to provide an apparatuswhich can combine a product, a transparent blister, and a blistersupporting card into a display package in one continuous operation.

Other objects, advantages and salient features of the present inventionwill become apparent from the following detailed description, which,taken in conjunc- -tion with the indexed drawings, discloses a preferredembodiment of the present invention.

Referring now to the drawings which form a part of this originaldisclosure:

FIG. 14 is a side elevational view similar to FIG. 11 but additionallyshowing the now formed display package being ejected from the 'suppoortassembly onto a second conveyor.

The foregoing objects are attained by providing an endless conveyor witha series of support assemblies, each including a box-like housing havingaligning rails on the top surface and movable spring fingers coupledthereto, capable of passing through slots in the aligning rails tosecure a card to the support assembly. An odd cam rail is provided onthe top surface for actuating glue heads to deliver an adhesivecomposition to the card. An elevating finger and ejecting finger, eachrotatably mounted through the sides of the housing, are capable of beingcammed upwards to respectively elevate a portion of a card and eject thefinished display package. Located on support surfaces on both sides ofthe conveyor are a series of cam rails to actuate the spring fingers,the ejecting finger, and the elevating fingers. Two fixed rods areprovided in overlying relationship to the conveyor and the housing forfolding one portion of the card onto a second portion thereof afteradhesive has been applied to the card. Rollers are provided forcompressing the folded card to form the final package and the ejectingfinger is then operated to discharge the package onto an ejectingconveyor. Conventional delivering devices can be used for feeding theblister supporting cards, the transparent blisters, and the products tothe support assemblies, but the details of these delivering devices formno part of the present invention. In a typical operation, a card, ablister, and a product are sequentially delivered to each supportassembly. Then, the card is secured to the assembly and adhesive isapplied to the top of the card. Next, a forward portion of the card iselevated and folded back onto the rear portion of the card. Then, thefolded portions are compressed together, with the adhesive between them,by means of rollers. Finally, the completed display package is ejectedfrom the support assembly.

Referring to the drawings in further detail, as shown in FIGS. 1 and 2,the apparatus for forming the display package includes an endlessconveyor 20 which has its upper run movable through a planar supportsurface 22 comprised of a right-hand surface 23 and a left-hand in turn,is rotated by a suitable drive motor (not 7 shown). The conveyor movesfrom the right to the left as seen in FIGS. 1 and 2.

Mounted above a first portion of the upper run of the endless conveyor20 are three conventional feeding devices for feeding blister supportingcards, transparent blisters, and the product to be displayed to asupport assembly 100 which is mounted on the conveyor 20, and which willbe described in detail hereinafter. A card-feeding device 34 ispositioned above the endless conveyor 20 adjacent the idler roller 28and can be any conventional sheet or article feeding device forindividually feeding a rectangular card onto the support assemblies 100.Adjacent the card-feeding device 34 is a blister feeding device 36 whichis any conventional device capable of individually delivering aconventional transparent blister onto the card which has previously beendeposited on a support assembly. A productfeeding device 38 is locatedabove the endless conveyor 20 adjacent the blister feeding device 36 andis any conventional device for delivering an individual product into thetransparent blister which is lying in a card which is located on the topof a support assembly. As will be described in more detail hereinafter,a card is delivered to one of the support assemblies 100 located on theconveyor 20, then a transparent blister is delivered to an aperture inthe card and finally a product is delivered to, and fills, the blister.The details of the feeding devices 34, 36, and 38 do not form a part ofthe present invention.

As seen in FIGS. 1, 2, and 10, two conventional adhesive applying glueheads 41 and 43 are supported above the middle of the endless conveyor20 in a position adjacent to the product-feeding device 38. These glueheads 41 and 43 are supported by a support rod 45 which is parallel tothe surface of the endless conveyor 20 and is mounted to the supportsurfaces 23 and 24 by means of upright posts 47 and 48.

A microswitch 49 is mounted to the left-hand support surface 24 adjacentpost 48 and has a cam rail follower 51 connected thereto. Themicroswitch 49 is connected to the glue heads 41 and 43 and whenactuated causes the glue heads to deposit glue in two continuous streamson the edges of a card moving thereunder, as will be describedhereinafter. Each glue head includes a supply reservoir in whichadhesive is stored and a de positing nozzle to which adhesive cangravitationally flow, and a valve normally preventing such flow.Operation of the microswitch 49 opens such valve.

Spaced further along the support surface 22 are two upright rods 53 and55 which support angle rods 57 and 58, respectively, lying parallel tothe surface of the endless conveyor 20 and extending over the conveyor.

Adjacent the upright rods 53 and 55 are two upright supports 61 and 63in the form of rectangular walls.

'Rotatably mounted on the supports 61 and 63 are two rods 65 and 66which are spaced from, and parallel, to each other and parallel to thesurface of the endless conveyor 20 and which further carry thereon intheir center, two rollers 68 and 69. The width of each roller ispreferably equal to the width of the blister supporting cards.

Spaced from the roller 69 is an endless ejecting conveyor 70 which hasits conveying surface oriented at an acute angle to the plane of thesurface of the endless conveyor 20. The ejecting conveyor 70 issupported between a small idler roll 71 adjacent the top of the supportassemblies 100 and a larger driven roll 73 elevated abovethe roll 71 sothat the conveyor 70 slopes upwardly. The drive roll 73 is connected bya drive belt 75 to the drive roller 30. The conveyor 70 runs in the samedirection and at substantially the same speed as the conveyor 20 andadjacent the upper end of the ejecting conveyor 70 is a platform oradditional conveyor 74 for receiving articles ejected from the conveyor70.

Referring to FIGS. 2 and 10, two cam rails 76 and 78 are slightly spacedfrom and parallel to the edges of the endless-conveyor 20 on the supportsurfaces 23 and 24, respectively, extending from a position adjacent theproduct-feeding device 38 to slightly past the upright rods 53 and 55.Each cam rail is elongated, and rectangular in cross-section, and isprovided with a downwardly sloping front end 81 and 82 as shown in FIG.10.

As seen in FIGS. 2 and 11, located adjacent and parallel to the cam rail76, between that rail and the edge of the endless conveyor 20, is asmaller cam rail 83 which extends from a position adjacent the uprightpost 47 to the upright rod 53 on the right-hand support surface 23. Camrail 83 is rectangular in cross-section and has a downwardly slopingfront end 84.

As seenin FIGS. 2 and 14, a fourth cam rail 85 is located on theleft-hand support surface 24 next to and parallel to the edge of theendless conveyor 20 between the support 63 and the front of the ejectingconveyor 70. This cam rail 85 also has a downwrdly sloping front edge 86which is similar to the other cam rails 76, 78, and 83.

Referring now to the support assemblies 100, a plurality of suchassemblies are connected at the middle of their bottom surfaces to theendless conveyor 20. Such assemblies are spaced from one another by apreselected distance.

As seen in FIG. 3, each support assembly is formed as a box-like housinghaving rectangular planar walls, including a top wall 103, a bottom wall105, a left side wall 107, and a right side wall 109, with each of theand 124 which pass completely through each aligning rail. An aperture orcutout 117 is formed through the top wall 103 between and spaced fromthe two aligning members 111 and 113. The shape of the cutout 117 can beas desired and is preferably in a configuration which matches theconfiguration of the transparent blister, as will be describedhereinafter.

Along the forward portion of the top wall 103 is a slot 119 whichextends from a position adjacent the ends of the aligning members to thefront edge of the top wall. The shape of the slot 119 can be as desiredas long as it allows a rod-like fingerto pass through it. On the leftside of the top wall 103 is an odd cam rail 121 which is parallel torail 113 and extends from the forward edge of the top wall adjacent theslot 119 rearwardly past the end of the slot 115 on the aligning member113. The rail 121 is provided with a slot 123 which is aligned with theslot 115 in the aligning rail 113.

A lug 125 mounted on the exterior of the side wall 107 has rigidlyconnected thereto, a right-angled spring finger 126. The finger 126includes afirst portion 127 having its bottom end mounted to the top ofthe lug 125 and includes a second portion 128 passing through the slot123 in the odd rail 121 and into the slot 115 in the rail 113. Attachedperpendicularly to the spring finger 126 is a rod 129 having an enlargedroller head or cam follower. 131 at its free end. A similar lug 125 ismounted on the exterior of the side wall 109 and it carries a similarspring finger having a free end or second portion 128 extending into theslot 124 in the rail 111. The free ends or second portions 128 of thespring fingers can move inwardly and outwardly through the slots 115 and124.

As seen in FIGS. 3 and 4, an ejecting finger 137 is rotatable mountedthrough an aperture in the left side wall 107. As seen in FIGS. 4 and14, the ejecting finger 137 has a first curved portion 139 whichconnects at right angles to a straight portion 141 which passes throughan aperture in the left side wall 107 and then connects at right anglesto an arm portion 143 which is parrallel to the surface of wall 107 andhas an outwardly facing enlarged head or cam follower 145 at rightangles to its free end. In an unactuated position, due to gravity, or ifdesired, a biasing spring, the free end of the curved portion 139 restson the bottom wall 105 of the support assembly 100. The curved portion139 is in a position between the left and right side walls 107 and 109such that it is aligned with the center of the cutout 117 in the topwall 103 and can pivot upward toward and through that cutout.

As best seen in FIGS. 3, 4, and 11, an elevating finger 147 is rotatablymounted on the right side wall 109 adjacent and forward the springfinger located thereon. This elevating finger 147 is of a similarconstruction to the ejecting finger 137 and is essentially a mirrorimage thereof. Specifically, the elevating finger 147 has a curvedportion 149 connected perpendicularly to a straight portion 151 whichpasses through an aperture in the right side wall 109 and isperpendicularly connected to an arm portion 153 which has an enlargedhead or cam follower 155 connected thereon and facing' away from theright side wall 109. The free end of the curved portion 149, as seen inFIG. 3, rests on the top of the bottom wall 105 in the unactuatedposition due to gravity or, if desired, by spring pressure. The curvedportion 149 is centered between the left and right side walls 107 and109, and is aligned with the center of the slot 119 so it can rotateupward, toward, and through it.

As shown in FIGS. 5 and 7, the blister supporting card 160 is preferablyrectangular in shape and has a cutout 161 in one portion correspondingin shape to the cutout 117 in the top wall 103 of the support assembly100.

As shown in FIG. 6, a typical blister 170 is formed from transparentplastic and has a bulged support section 171 formed in the shape of theproduct to be carried therein and a flange portion 173 surrounding theedge of the support section 171.

In operation, the card-feeding device 34 is filled with theblister-supporting cards 160, the blister-feeding device 36 is filledwith the transparent blisters 170, and the product-feeding device 38 isfilled with products 180 to be packaged. The drive motor operates theendless conveyor 20 and the ejecting conveyor 70. The card-feedingdevice 34 is synchronized with the movement of the endless conveyor 20so that as a support assembly moves underneath the card-feeding device,a single card is dropped from the feeding device 34 onto the top wall103 of the support assembly so that the side edges of the card arebetween the aligning members 111 and 113, and the cutout 161 in the rearportion of the card is aligned with the cutout 117 in the top wall 103of the support assembly. Preferably, the length of the card 160 will beabout equal to the length of the top wall 103. This position is shown inFIG. 7. As the conveyor 20 moves from the right to the left as shown inFIG. 1, a blister is dropped from the blister feeding device 36 into thecutout 161 on the card 160 with the support section 171 thereinprojecting through the card cutout and into the cutout 117 in the topwall 103. This is shown in FIG. 8 wherein the flange portion 173 restson the surface of the card 160 and supports the depending supportsection 171 below the card and in the cutout 117 in the top wall 103. Asthe conveyor 20 moves further to the left, a product is dropped from theproduct-feeding device 38 into and filling the blister support section171. This is shown in FIG. 9. As used herein, the term filling does notrequire that the product 180 completely fill the blister 170, andinstead, is merely used to distinguish a filled blister from an emptyone.

As the support assembly 100 moves further along past the product-feedingdevice 38, the cam followers 131 connected to the spring fingers 126engage the sloping ends 81 and 82 of the cam rails 76, and 78, and areelevated to run along the top surface of these cam rails. This elevationof the cam followers causes a concommitant inward rotation of the springfingers 126 which causes their free end portions 128 to move through theslots 115, and 124, and into an overlying relationship with the card 160lying on the top wall of the support assembly, as shown in FIGS. 2, and10. This action secures the blister-supporting card 160 to the topsurface of the support assembly to prevent it from shifting.

As each support assembly 100 moves further along the support surface 22,the odd rail 121 located thereon engages and moves the cam rail follower51 connected to the microswitch 49. This closes the microswitch 49 andactuates the glue heads 41 and 43 causing them to deliver two stripes ofadhesive compositon along the edges of the top of the rear portion ofthe blister-supporting card 160 as shown in FIG. 10.

Also, as the support assembly 100 moves along the support surface, thefollower 155 on the elevating finger 147 engages the top surface of thecam rail 83 which causes the curved portion 149 thereon to rotateupwardly through the slot 119 and into engagement with the bottom of theforward portion of the blistersupporting card 160. This rotation andengagement, as shown in FIG. 11, raises the forward portion of the card160 to a height above the angle rods 57 and 58. Since the middle of thecard 160 is held in place by the spring fingers 126 as discussed above,the forward movement of the conveyor 20 causes the bottom of the raisedportion of the card 160 to engage the angle rods 57 and 58 and pivotaround the spring fingers 126 as the assembly 100 moves past the anglerods. This is shown in FIG. 12. If desired, the card 160 can beprescored or prefolded centrally, as shown at 162 in FIG. 5, tofacilitate folding.

Thus, the forward portion of the card 160 is folded over onto the rearportion and the card then proceeds to move under the rollers 68 and 69which press the forward portion of the card onto the rear portion of thecard which has adhesive thereon. This causes the forward portion of thecard to become adhered to and fixed to the rear portion of the cardwhich contains the blister and the product. The blister flange 173 issandwiched between the folded card portions, thus locking the blister170 in position. At this time, the followers 131 associated with thespring fingers 126 reach the ends of the rails 76 and 78, and disengagefrom them allowing the spring fingers to rotate out of engagement withthe top of the card 160.

As seen in FIG. 14, as the support assembly 100 continues to move alongwith the endless conveyor 20 past the rollers 68 and 69-, the follower145 on the ejecting finger 137 rides up the sloping end 86 and movesalong the fourth cam rail 85. This causes the curved portion 139 of theejecting finger to rotate upwardly through the cutout 117 and into anengagement with the bottom of the blister 170. Since the spring fingers126 have previously been released from their engagement with the card160, nothing prevents the card 160 from being elevated upwardly bycontact with the curved portion 139. As this happens, the bottom of thecard 160 engages the forward end of the ejecting conveyor 70, is liftedfrom the top wall of the support assembly 100, and is carried along thelength of the ejecting conveyor 70. After movement along the conveyor70, the now completed display package is delivered to the platform orcontainer 74. The conveyor 70 can be formed as two separated bands witha central space through which the blisters 170 can travel while the cardedges are supported on such bands.

This operation is continued for successive support assemblies 100 andautomatically forms any desired number of display packages.

While the invention has been described above with the blister being fedto an aperture in the card and then the product fed into the blister, itis possible for the product to be frictionally secured to the inside ofthe blister and the blister then fed to the portion of the card nothaving the aperture. In this case, the portion having the aperture isfolded over the blister and the product resting on the other portion ofthe card. Thus, the need for the cutout 117 in the support assemblycould be eliminated.

Additionally, the precise sequence of the operation can be altered byvarying the length and position of the various components of theapparatus. Therefore, although the invention has been described with theadhesive being deposited essentially on only the rear portion of thecard, the entire card can receive adhesive strips by varying the lengthof the odd rail and the position of the microswitch, or the position ofthe glue heads.

While one advantageous embodiment has been chosen to illustrate theinvention, it will be understood by those skilled in the art thatvarious changes and modifications can be made therein without departingfrom the scope of the invention as defined in the appended claims.
